So our vase here is a cylinder, right?
With its top missing.
How would we calculate the surface area of this shape?

nirmalnema · Answer

lateral surface area =2 pi rh + area of circle = pi* r *r =3000

miracrown · Answer

Our cylinder has two parts here, right?
The vertical side and the bottom.

miracrown · Answer

And the area of the vase would just be the sum of the area of those two parts, right?

miracrown · Answer

So let's calculate the area of those two parts.
How would we calculate the area of the bottom of the vase?
